Carries both pedal trays and lets them slide fore and aft for per-driver adjustment.
A rail welded into the frame that the trays clamp to. Sliding the tray and locking the clamping handle sets pedal position without tools.
No part-specific design process is documented. The Pedals subsystem design process applies: 1. Take brake and throttle pedal position ranges from the ergonomics study (brake optimum 38.22 in, throttle optimum 38.48 in; CR26I sits at 38.7 in and 38.5 in). 2. Select the pedal ratio from the master cylinder sizing and the required pedal force, then set the geometry that achieves it. 3. Analyse the arm. CR26I brake arm: 225 lbf applied, fixed at the hinge, minimum FoS 1.23, with a mesh convergence study. 4. Waterjet the arms, lay up the faces, assemble on the rail. 5. Validate pedal force and travel against the brake calculation on the car.
Steel, welded into the frame.

Added 1.61 lb to the CR26I frame; accepted because per-driver pedal position is an ergonomics requirement. Cut pedal adjustment time 60%, from 3:00 to 1:45. From the cost report drawings and CAD: Weighed mass: 147.7 g (0.326 lb). CAD mass, CR22 master assembly: 0.302 lb (0.137 kg), 2 instances, 0.603 lb total. CG at X 8.46 in, Y 0.25 in, Z 3.94 in in vehicle coordinates.
